Hello!

Im trying to learn how to read files from SD card im M221 controller.

Currently i have set it up to log two analog inputs on a timer.'

I can not fint any way to export, acess or transfer. 

Anyone tried this?

Anyone have other tips on how to extract data from this plc type? I want to display some analog data to a website or souch.

what ports do you have on the m221? Ethernet? 

I have recently just played around with node red and modtcp/ip and a m340. I could read and write to the m340 via node red. 

From node red you can send the data to whatever you want (Well mostly)

If the m221 has ethernet you can also use the mdtcp/ip node and collect the data from the m221

That worked very well 🙂
